QUESTION
I have been experimenting with RFECV on the Boston dataset.
My understanding, thus far, is that to prevent data-leakage, it is important to perform activities such as this, only on the training data and not the whole dataset.
I performed RFECV on just the training data, and it indicated that 13 of the 14 features are optimal. However, I then ran the same process on the whole dataset, and this time around, it indicated that only 6 of the features are optimal - which seems more likely.
To illustrate:

Answered 2021-Feb-19 at 16:40It certainly seems like unexpected behavior, and especially when, as you say, you can reduce the test size to 10% or even 5% and find a similar disparity, which seems very counter-intuitive. The key to understanding what's going on here is to realize that for this particular dataset the values in each column are not randomly distributed across the rows (for example, try running X['CRIM'].plot()
). The train_test_split
function you're using to split the data has a parameter shuffle
which defaults to True
. So if you look at the X_train
dataset you'll see that the index is jumbled up, whereas in X
it is sequential. This means that when the cross-validation is performed under the hood by the RFECV
class, it is getting a biased subset of data in each split of X
, but a more representative/random subset of data in each split of X_train
. If you pass shuffle=False
to train_test_split
you'll see that the two results are much closer (or alternatively, and probably better, try shuffling the index of X
).
QUESTION
Background: I'm using a Perl script that submits abuse reports to abuseipdb.com. The script has only one default category (14 Port Scan), but I want to submit the correct category/categories for the abuse reports. Submitting the category is done by a number. Multiple categories are possible and are separated by a comma ','.
List of categories: https://www.abuseipdb.com/categories
Source of the script: https://www.abuseipdb.com/csf, scroll roughly halfway down for "abuseipdb_report.pl".
I've modified the script to scan the log files for keywords and if found give it a correct category number. (Disadvantage: only 1 category number can be used this way.)
It's working, but far from pretty. All those if and elsif statements will take a lot of processing time.
Here are the snippets that I've cooked up. (it's working!)

QUESTION
I have just installed ModSecurity on IIS 10.0 running on Windows 10. However even a "clean" install generates a lot of errors only by visiting the default IIS site.
By looking at eventvwr
and making a single request I get a total of 14 new errors for a GET request to localhost
.
Every event has the following description:
The description for Event ID 1 from source ModSecurity cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:

Answered 2017-Mar-28 at 13:00Regarding the description I found this:
This is just an warning. That is actually the ModSecurity letting you know something about a given request. The "windows description" of the event can be ignored. Look at the content...
